US pop rockers the Jonas Brothers have been growing their UK fanbase.

Nick, 14, Joe, 17, and 19-year-old Kevin recently opened for Avril Lavigne at her gig in London.

Nick began singing at the age of six, and the brothers were signed as a group in 2005.

Now they share the same manager as Justin Timberlake.

Their self-titled debut album, released in August 2007, has gone on to achieve platinum status.

And the Jonas Brothers star in the upcoming Disney Channel Original Movie, Camp Rock, and in the Disney Channel series, JONAS!
